Abstract

Novel strain evaluation method is proposed, which is based on the strain dependence of the excitonic transition energy. Comparing the excitonic transition energies measured by the photocurrent spectroscopy with the calculated energies c-axis strain in undoped GaN grown on SiC substrate was estimated to be -0.03%.
